Abstract

A 32x32 visual motion sensor based on the time stamped pixel structure is proposed. The sensor pixel is formed by a time stamp component and a compact spatial based edge detector with a pixel size of 70x70μm² in standard 0.35μm CMOS process. It measures up to 6000 degree/s with focal length f = 10mm. Less than 5% rms variation for middle range velocity measurement and less than 10% rms variation for high and low velocity measurement have been achieved. This structure is good for scaling down with new fabrication processes to implement large scale 2D arrays with low power consumption in the near future.
